Yes.  The leak (through 1800) was fixed rather quickly, but the
routes stuck.  The fact that many (most?) of them were more specific
routes made the whole thing as "eventful" as it was; normally, selection
by path length means that leaks like that don't have any particular
effect.  Hence, you actually had three things go wrong at the same time:

1) Wrong filtering.
2) More specific routes.
3) The routes stuck after withdrawal.
